Final Cut Pro – Edit on the Go
High-speed edits with one keystroke.
Did you know that you could add edits to a clip while playing the Timeline? This is perfect for cutting to the beat of the music.
Here’s the trick: press Control+V as the playhead moves across the clip. Final Cut adds red markers as you go, and then does the edits when you stop playback.
You can even do this while the playhead is parked, by typing Control+V.
